局间信令在中继线路上传输,用于协商通话需要的媒体资源
信令就是交换设备之间的呼叫接续协议
七号信令是固话网络、移动通信网络重要的支撑系统
共路信令可以为多个话路同时提供信令传输服务
mtp3是7号信令的信令网功能级,为了路由信令消息,mtp3使用信令点编码来进行消息寻址和路由
tup在信令传输中使用cic来区分各个呼叫的信令,sip可以使用call-id来进行区分
交换设备中的呼叫处理与信令处理这两大软件模块最好设计为松耦合,这样在进行信令模块替换时可以做到方便灵活
我国的信令网采用三级结构
信令网是现代通信网的三大支撑网络之一
sip与七号信令进行转换时,需要将invite消息中sdp的媒体端口号取出,放入七号的iam消息
sip 已被3gpp采纳为ims的协议标准之一
随路信令在话路中传送,用户拨打电话银行时输入的帐号密码就是在随路信令里传送的
共路信令提供了高速信令传输通道,用户拨打电话银行时输入的帐号密码在这个通道中传输
mtp1是七号信令的数据链路级,它起到了物理层的作用,通常的传输带宽为64kb/s,这是由局间专用的物理线路来提供的
mtp2是七号信令的链路层,它是硬件电路来完成的,没有复杂的软件状态机
mtp1的通路是专用的,不能经过tst的交换网络
mtp2的功能主要是保证信令单元的正确传输,它不涉及流量控制
七号信令与voip信令不一样,七号信令只负责主叫号码和被叫号码传输、被叫状态的传递,媒体信息不进行协商
双音频的dtmf信号、直流脉冲信号、fsk的来电显示信号和七号系统的iam信号都属于模拟用户信令
tup信令仅用于支持局间电话呼叫接续,用户的业务是不需要信令进行支持的
sip是ietf制定的ip电话信令协议,只能用于语音通信
sip信令在进行sdp协商时,会确定双方的音视频编码、rtp端口等信息,而接收媒体流的ip地址不用协商
